Christian Teyssier

I am interested in tectonic processes, including subduction, collision, crustal thickening, partial melting of crust, orogenic collapse, and the development of continental and oceanic core complexes. Our research group combines structural geology, metamorphic geology, geochemical and geochronological techniques, numerical simulations, microstructural and microfabric analyses using electron backscatter diffraction, and rock and mineral experiments. Current research topics include the hydration of oceanic lithosphere in relation to oceanic core complexes and transform shear zones, the flow of partially molten crust in orogenic plateaux and metamorphic core complexes, the exhumation mechanisms of high-pressure rocks in subduction complexes, the exhumation of subducted continental crust and ultrahigh-pressure rocks, and the coupling between subducted slab dynamics and crustal-surface processes in active tectonic regions. Current field areas include the North American Cordillera, the Alpine belt in the Aegean and Anatolian domains, the Norwegian Caledonides, and the Variscan belt of western Europe.
